JOHN B. KENISON, OF LYNN, MASSACHUSETTS.

STREET-SANDNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 393,374, dated November 27, 1888.

Application filed DeceinberQO, 1886. Renewed May 5. 1888. Serial No. 272,965. (No model.)

To @ZZ whom it may concern:

Be it known that I, J oHN B. KENrsoN, of Lynn, in the county of Essex and Commonwealth of Massachusetts, have invented certain Improvements in Street-Sanding Machines, of which the following, taken in connection with the accompanying drawings, is a specification.

This invention relates to means for sanding the sidewalks of ordinary city and town streets, and the nature thereof is fully described and specifically claimed hereinafter.

Referring to the drawings, Figure lis a side elevation of the device embodying my invention. Fig. 2 is a rear end elevation of the View of the sand-hopper.

The hopper A may be mounted upon anordinary carriage running-gear. At the bottom of the hopper is an outlet or opening,a,which 1s opened by lifting and closed by depressing the vertically movable slide -plate I). Said plate b is connected, as shown, with the angular lever d, from which a rod, e, extends forward to the drivers seat, (not shown,) the arrangement being such that the operation of lifting and depressing the plate b may be effected by a suitable movement of the rod aand this may be done by the foot or hand of the driver, as best suits his convenience. The sand exhausts from the hopper through the opening c into the pipe B, and is thereby conducted downward into the box C, and leading from the blower E is an air-pipe, D, that also opens into the box C directly under the end of pipe B in such manner that the sand is deposited from pipe B into the air-current issuing from pipe D. The sand is carried forward and forced with the air out of theend of box C and distributed over the sidewalk.

On the axle wheel F, or securely fixed thereto, is the wheel H, from which motion is communicated by a chain belt, f, to shaft 7i. Said shaft h is adapted to be revolved in its supporting-frame, as shown, and carries a wheel, n, from which motion is communicated through suitable belt, t, to turn the blower or fan-wheel (not shown) located in the blowerease E. This indirect manner of belting from wheel F to'the blower is employed by me in order to obtain the desired velocity of the blower. I would not, however, be understood Fig. 3 is a sectional as saying that it could only be done this way. On the contrary, the blower could be made to revolve by clock-work, or by steam-power or other obvious means, in which case the wheels of the vehicle could be dispensed with and runners used instead.

In the sand-hopper A is a iinger, 4, attached to the bell-crank lever 5, which lever bears one end upon the periphery of wheel n, the object being to stir the sand in the hopper by reciprocating the lever 4, and thus prevent the outlet a from getting clogged. The necessary motion is imparted to the linger by cams 6 on the periphery of wheel n, and a spring, 7, ou the hopper to bear down the lever 5, as represented.

In use the vehicle on which the distributing device is arranged is moved along the street close up to the sidewalk, while the sand is blown outward from the box or tube C and carried by the air-current over and allowed to fall upon the sidewalk. To insure the better distribution of the sand, I make the inner bore of the box or tube C rectangular, as shown. It is at times desirable to stop the flow of the sand, also the air-current,to avoid pedestrians;

and to this end I put a slide or cut-off in the air-pipe at point 8, and from this slide is a 1ever, 9, extending forward to the drivers seat, (not shown,) and by an obvious operation of this lever the driver can at will open and close the slide or damper. The sand may be stopped by depressing the slide-plate b, as before stated.

I claiml. In a sanding-machine, a hopper, a discharge-pipe, B, leading therefrom, a blower, a discharge-pipe, 8, therefor extending into a position below the discharge-opening of the pipe B, the opening of said pipe 8 being dattened or of greater horizontal dimension than the opening ofthe pipe B, whereby the blast of air reaches from side to side beyond the opening of the pipe B, substantially as described.

2. In combination, the hopper, the distributing-box C, the discharge-pipe B, extending into the box and of less diameter than the width of the box, the blower, as E, and the dischargepipe, as 8, having its dischargeopening inthe box G beneath the opening of the pipe B, and extending from side to side of the distributingbox, substantially as described.

3. In asandinghinehine, u sund-hopper propulley of the 12in und adapted to bear upon the vided with a conveyer-pipe opening into a ds same, said pulley being provided with a series tribubing-box, a fun 'also having u eonveyerof cams or irregular projections, which cause pipe opening :into the distributing-box below the arm of the bell-crank lever to rise'and fall I5 bhe sund-conveyer, u shaft driven by traction i during the revolution of the pulley, whereby und provided with u suitable pulley, u driv the contents of the hopper are continually ing-belt3 between said pulley and the pulley of stirred, substantially as described.
